This slightly modified version of Alan Cox's ping patch has been tested onmy SMP test box. Without it, I can crash it from a Win95 box, and thensoftdog (I assume) reboots it. With the patch, Win95 doesn't seem able tocrash it. I'm now running this patch on 5 other systems.

Is there anything other than someone trying to crash my box that wouldtrigger the printk I added? One of our servers just logged this:

Oversized packet received from 205.229.51.6

That's one of our dialup user IP addresses. Are my own users trying tocrash me, or is it just a Windows IP bug? If there's no explanation otherthan someone trying to crash our mail server, I'd like to terminate thataccount.
